GLASS & COATING
Anti-Fingerprint & Waterproof Nano-Coating Technology has been applied to the Variable Neutral Density + CPL filter system to protect the glass from the unpredictable factors that all photographers and filmmakers face when shooting outdoors. The coating helps with beading and any excess droplets can be easily removed with a lens cloth without the fear of eliminating any of the coatings and without leaving stubborn smears on the glass.
The German Schott B270® glass also includes Anti-Reflective coatings, which virtually eliminate all flare and reflections from the front and rear surfaces. This helps visible light to pass through the glass by removing unwanted reflections, giving the user the best possible light transmission (up to 97%), optimizing images for the sharpest possible outcome. Whether shooting at 16mm or 400mm, the glass and coatings used in this Variable Neutral Density + CPL filter system produce sharp images, even at light reductions of up 10 stops. Each side of the glass has 9 layers of the above coatings applied.
